Water reacts with carbon dioxide in the air to form small amounts of carbonic acid. In a sodium hydroxide solution, this reacts again to form sodium carbonate.

How do you distinguish sodium hydroxide and sodium acetate?
To test presence of Sodium ions, do a flame test: color observed: golden yellow. To test presence of carbonate or hydrogen carbonate ions: Take some of the sodium hydrogen carbonate in a dry test tube. Heat the test tube and bubble the gas through limewater. Limewater turns milky. Carbonate or hydrogen carbonate ions present. To distinguish between carbonate and hydrogen carbonate: Add indicator solution. If colour of solution turns green, pH is 7-8, hydrogen carbonate ions are present. If colour of solution turns blue, pH is 12-13, carbonate ions are present. -Iberuz
What observations do you make when you react potassium hydroxide with sodium carbonate?
You get a double decomposition reaction, producing sodium hydroxide and potassium carbonate, but actually there is no real reaction; the four substances remain in perfect equilibrium in solution.
Is sodium hydroxide solution neutral?
No. A sodium hydroxide solution is very basic.
A solution of sodium carbonate Na2CO3 that has a molarity of 0.0100 M contains equivalents of sodium ions per liter of the solution?
0.01 mole
What happens when sodium hydroxide solution is added to calcium carbonate and then warmed?
CaCO3(s)+2NaOH(aq)--->Ca(OH)2(aq)+Na2CO3(aq) When you heat it later, the water in the solution evaporates leaving you with just the salts. Also, it is better to say, calcium carbonate is added to sodium hydroxide solution as you add a solid to a solution not really vice versa.
What does 1M solution of sodium carbonate mean?
A 1M solution of sodium carbonate contains 1 gram formula mass of sodium carbonate dissolved in each liter of solution.

What happens if you put sodium carbonate solid on ammonium hydroxide solution?
In a weak solution, fizzing. In a very strong solution - run away.
Is sodium hydroxide unknown solution?
Sodium hydroxide is not an unknown solution.
Is sodium hydroxide solution neutral?
No. A sodium hydroxide solution is very basic.

What has the highest pH value acetic acid or sodium hydroxide or sodium carbonate or sulphuric acid?
sodium hydroxide

What are the ingredients in liquid plumber?
The Clorox company's product Liquid-Plumr contains the following ingredients: water, sodium hypochlorite, sodium chloride, sodium hydroxide, sodium carbonate, and sodium silicate.
What are three examples of base?
Sodium hydroxide Sodium carbonate Sodium bicarbonate
Can you detect a mixture of sodium hydroxide sodium carbonate and sodium bicarbonate?
yes
